Startle and blink reflex in high functioning autism
Neurophysiologie Clinique/Clinical Neurophysiology, 2016An important clinical feature of autism is the presence of atypical responses to sensory stimuli. In this study, we investigated if high functioning autistic patients had abnormalities in the blink reflex and the startle reaction to auditory or somatosensory stimuli. Fourteen patients aged between 7 and 16 years were included in the study.

Emotion, novelty, and the startle reflex: Habituation in humans.
Behavioral Neuroscience, 1993Previous research with both animal and human subjects has shown that startle reflex magnitude is potentiated in an aversive stimulus context, relative to responses elicited in a neutral or appetitive context. In the present experiment, the same pleasant, unpleasant, and neutral picture stimuli were repeatedly presented to human subjects. Startle reflex

Caffeine and prepulse inhibition of the acoustic startle reflex
Psychopharmacology, 1999A stimulus presented immediately prior to a startle reflex-eliciting stimulus inhibits the startle reflex. This is termed prepulse inhibition (PPI) and is postulated to index automatic and controlled attentional processing of the prepulse.Two experiments investigated the effect of 0, 2, and 4 mg/kg oral caffeine on PPI of the acoustic startle eyeblink ...

Winter is coming: Seasonality and the acoustic startle reflex
Physiology & Behavior, 2017Circannual rhythms and seasonality have long been in the interest of research. In humans, seasonal changes in mood have been extensively investigated since a substantial part of the population experiences worsening of mood during winter. Questions remain regarding accompanying physiological phenomena.

Affective modulation of the startle reflex in schizophrenic patients
European Archives of Psychiatry and Clinical Neuroscience, 1995Startle-elicited blinks were measured during the presentation of affective slides in order to investigate emotional responsiveness in 24 male healthy subjects and 34 male schizophrenic patients. Although the two groups did not differ with regard to their subjective and autonomic responses to the slide stimuli, there was a significant difference between

[The startle reflex in schizophrenia research].
Der Nervenarzt, 2002Abnormalities of attention and information processing are described as important features of schizophrenia. Theoretically, they may reflect deficiencies in central mechanisms of inhibition and selection. These deficiencies are believed to lead to cognitive fragmentation in patients with schizophrenia.

DIRECTIONAL FREE FIELD STARTLE-REFLEX AUDIOMETRY
Archives of Otolaryngology - Head and Neck Surgery, 1954CURRENT audiometric techniques in infants and children have been directed along objective lines. Research in skin-resistance electroaudiometry and electroencephalographic arousal responses are outstanding examples of this laudable trend. Experienced observers, however, realize some of the shortcomings of these techniques and base their hearing ...
